Abstract

PROCEDIMIENTO PARA LA REDUCCION DE CLOROFLUOROCARBONOS EN UNA CELDA ELECTROLITICA, CELDA PARA LLEVAR A CABO DICHA REDUCCION Y PROCEDIMIENTO PARA LA ELIMINACION DE LOS SUBPRODUCTOS FORMADOS EN DICHA CELDA. EN EL PROCEDIMIENTO PARA LA REDUCCION ELECTROLITICA EL O LOS ANODOS SON DE DIFUSION DE HIDROGENO. PREFERIBLEMENTE, LOS ANODOS SON MEMBRANAS PERMEABLES AL HIDROGENO QUE COMPRENDEN PALADIO METALICO. EL PROCEDIMIENTO PARA LA ELIMINACION DE LOS SUBPRODUCTOS FORMADOS EN DICHA CELDA COMPRENDE LA ABSORCION DE HIDRACIDOS, LA INCINERACION DE HIDROCARBUROS Y LA ABSORCION DE LOS PRODUCTOS DE INCINERACION. PERMITE TRATAR DIFERENTES CFCS Y MEZCLAS DE ESTOS Y DE OTROS CONTAMINANTES HALOGENADOS, COMO LOS PESTICIDAS, LOS DERIVADOS HALOAROMATICOS Y LOS POLICLOROBIFENILOS (PCBS).
